saying something about studying why we get disease. Then it says
something about Darwinism. However, I could not decipher any
absolute connection between how evolution helped because we
already know about mutations causing problems and we don't need
evolution for that.

So mutations never lead to evolutionary changes?

Mutations are a defect not evolution.

Mutations are change, not all negative. The ones that make a life form slightly stronger or more resistive to heat for instance, make more like them, they reproduce and sometimes lead to a whole new species. That is the essence of evolution.

Mutations can be driven by changes in the environment, food supply, many things.
